This plugin works where the built in firefox html 5 blocker does not (no matter how I configure it) which would normally mean 5 stars.

However it also for some reason blocks web fonts. As a developer that is a big issue for me and as a developer I have no idea why this html5 blocker would prevent webfonts from loading.

Because it works well 5 stars because it breaks websites fonts -3 stars

Great! Can you please make an option to block only video looping (separately from autoplay and preload)!!!??? You would save millions of users from crazy ads! :) This should be a must!

Niech Cię Bóg (wybierz sobie który) błogosławi za to rozszerzenie :)

I have to DISABLE or REMOVE this extension in order to allow preloading to occur. "Pause Autoplay" and "Disable Preloading" check boxes do not function for individual sites.

Stops annoying autoplay on Yahoo sites while none of the Firefox autoplay settings work (including Options, about:addons, about:config)

Doesn't seem to allow manually adding domains. Having to visit every domain individually is a pain. Not for me.

I'm glad to have this, to stop autoplay videos at Yahoo News. Unfortunately, it has no effect at YouTube, or many other media sites.

Doesn't work, unfortunately.

The extension works inconsistently.

Finalement un moyen efficace de bloquer les vidéos sur yahoo qui se lancent toutes seules, que ni le réglages du module Flash, ni le passage en "false" du media.autoplay.enabled dans l'about:config de Firefox ne géraient...
Merci !

Works like a charm! Thanks

No matter what, it'll always prevent a page from preloading. Even when you set a page to preload. Which prevents proper use of Youtube.

It works MOST of the time with YouTube. I usually have to reload the video page for it to kick in.

Worked great for the most of 2018. Then the videos started autoplaying again... CNN, ESPN. Uninstalled today and am currently using another autoplay disabler

Doesn't work for me. It's a shame there is only one app to choose from. Opera/Chrome offer several.

Add-on works, it stopped autoplay on iz.ru)

Causes many video streams to fail, throwing the following JavaScript error: "This video cannot be played due to a technical error.(error 200001)"

I'm using waterfox, the add-on works by stopping the htm5 video autoplay, but it doesn't stop video buffering, I can live with this limitation, but the biggest issue that made me uninstalling the add-on is the add-on somehow lags the browser when enabled. FYI I have multiple tabs opened with tabmixplus add-on. Also, the toolbar button UI is a bit buggy (maybe it's waterfox compatibility issue)
